The USB 2.0 signals +are connected to a PHY providing one host-only port and one OTG port. +The USB 3.0 signals are connected to two USB3.0/PCIE/SATA combo PHY. + +The ODROID M1 has 2 type A USB 3.0 connectors, with the USB 3.0 signals +connected to the two combo PHYs. For the USB 2.0 signals, one connector +is connected to the host-only PHY and uses the same power switch as the +USB 2.0 ports. The other connector has its own power switch and is +connected to the OTG PHY, which is also connected to a device only +micro-USB connector. The purpose of this micro-USB connector is for +firmware update using the Rockusb vendor specific USB class. Therefore +it does not make sense to enable this port on Linux, and the PHY is +forced to host mode. + +Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> +Tested-by: Dan Johansen <strit@manjaro.org> +Link: https://lore.kernel.org/r/20220930051246.391614-11-aurelien@aurel32.net +Signed-off-by: Heiko Stuebner <heiko@sntech.de> +--- + .../boot/dts/rockchip/rk3568-odroid-m1.dts | 49 ++++++++++++++++++- + 1 file changed, 48 insertions(+), 1 deletion(-) + +diff --git a/arch/arm64/boot/dts/rockchip/rk3568-odroid-m1.dts b/arch/arm64/boot/dts/rockchip/rk3568-odroid-m1.dts +index 2e4cc20bd676..9a84a7e76d7a 100644 +--- a/arch/arm64/boot/dts/rockchip/rk3568-odroid-m1.dts ++++ b/arch/arm64/boot/dts/rockchip/rk3568-odroid-m1.dts +@@ -127,6 +127,30 @@ vcc5v0_usb_host: vcc5v0-usb-host-regulator { + regulator-max-microvolt = <5000000>; + vin-supply = <&vcc5v0_sys>; + }; ++ ++ vcc5v0_usb_otg: vcc5v0-usb-otg-regulator { ++ compatible = "regulator-fixed"; ++ regulator-name = "vcc5v0_usb_otg"; ++ enable-active-high; ++ gpio = <&gpio0 RK_PA5 GPIO_ACTIVE_HIGH>; ++ pinctrl-names = "default"; ++ pinctrl-0 = <&vcc5v0_usb_otg_en_pin>; ++ regulator-min-microvolt = <5000000>; ++ regulator-max-microvolt = <5000000>; ++ vin-supply = <&vcc5v0_sys>; ++ }; ++}; ++ ++&combphy0 { ++ /* Used for USB3 */ ++ phy-supply = <&vcc5v0_usb_host>; ++ status = "okay"; ++}; ++ ++&combphy1 { ++ /* Used for USB3 */ ++ phy-supply = <&vcc5v0_usb_otg>; ++ status = "okay"; + }; + + &cpu0 { +@@ -490,7 +514,7 @@ usb { + vcc5v0_usb_host_en_pin: vcc5v0-usb-host-en-pin { + rockchip,pins = <0 RK_PA6 RK_FUNC_GPIO &pcfg_pull_none>; + }; +- vcc5v0_usb_otg_en_pin: vcc5v0-usb-otg-en-pin { ++ vcc5v0_usb_otg_en_pin: vcc5v0-usb-dr-en-pin { + rockchip,pins = <0 RK_PA5 RK_FUNC_GPIO &pcfg_pull_none>; + }; + }; +@@ -600,6 +624,11 @@ &usb_host0_ohci { + status = "okay"; + }; + ++&usb_host0_xhci { ++ dr_mode = "host"; ++ status = "okay"; ++}; ++ + &usb_host1_ehci { + status = "okay"; + }; +@@ -608,6 +637,24 @@ &usb_host1_ohci { + status = "okay"; + }; + ++&usb_host1_xhci { ++ status = "okay"; ++}; ++ ++&usb2phy0 { ++ status = "okay"; ++}; ++ ++&usb2phy0_host { ++ phy-supply = <&vcc5v0_usb_host>; ++ status = "okay"; ++}; ++ ++&usb2phy0_otg { ++ phy-supply = <&vcc5v0_usb_otg>; ++ status = "okay"; ++}; ++ + &usb2phy1 { + status = "okay"; + }; +-- +2.35.1 + |
